unable to install packages("caret") completely in R version 3.2.3

Question

> require("caret")
  Loading required package: caret
  Loading required package: lattice
  Loading required package: ggplot2
  Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck =      vI[[j]]) : 
   there is no package called ‘pbkrtest’

So I found that there is lack of "pbkrtest" then I tried to reinstall it.

> install.packages("pbkrtest")
 Installing package into ‘C:/Users/ADMIN/Documents/R/win-library/3.2’
 (as ‘lib’ is unspecified)

 There is a binary version available but the source version is
 later:
     binary source needs_compilation
 pbkrtest  0.4-2  0.4-3             FALSE

2: In install.packages("pbkrtest") :

It seems like that the installation keeps failing. As a result, I couldn't use other code using caret packages.

Answer 1

I faced this problem as well on Windows 7. I did following steps in the sequence and it worked. a) Make sure your R version is updated latest R release 3.2.3 b) The default sources seems to be installing Unix version. So I manually downloaded https://cran.r-project.org/web/packages/pbkrtest/index.html for windows c) Use manually install function from R menu to install the package.
